Stephen Anthony Hough, then aged 17, told police he’d been “masturbating in his car” before admitting he’d been siphoning petrol from a vehicle in Flint on the night of the 15-year-old’s disappearance on January 7, 1976.

He was among all local men aged between 17 and 22 who were asked by police to account for their movements in the hunt for the teenager’s killer.
